| 概要 |
The integrated use of symbolic and numeric technologies is presented through application examples in automotive industry. The effectiveness of such an integrated approach is emphasized by showing conc...rete uses of symbolic manipulation and numerical computation in Maple [1]. In the first of the two examples, the chemical equilibrium of combustion phenomena which is a constrained optimization problem is analysed symbolically and turned into an unconstrained optimization problem. As opposed to numeric-only approach, target equations for the minimization problem are explicitly shown, which facilitates the understanding of the problem. In the second example, a simple phenomenological model for the heat release process of an internal combustion engine is introduced where a differential equation containing a conditional branch is symbolically analysed and then numerically integrated to obtain some key physical quantities of the combustion dynamics. Finally, the paper is concluded with some remarks on challenges that modelling technologies in automotive industry are facing.続きを見る
